The Jebel al‐Ma'taradh and its surroundings contain exceptional deposits of lithic raw materials, including flint and chert, but especially chalcedony, agate, carnelian, and chrysoprase. These deposits were intensively exploited during the Neolithic, and some of the artefacts produced entered the trade network that included settlements on the coast and inland, sometimes as far as 300 km. During earlier periods, probably as early as the Pleistocene, only flint was used. Between the sixth and the fourth millennia, carnelian and agate were exploited to make beads, which are found in the necropolises and settlements of the UAE.  相似文献

In this paper we present the results of surveys carried out in February 2016 along a palaeo‐drainage system near the village of Bisyah. We report first on the geological prospection, which was our main goal, and then present our discovery of the only known localities in north Oman of large Kombewa flake production (>10 cm up to 20 cm). Among the scatter of artefacts, we found cores and large Kombewa flakes with two opposed bulbs of percussion, a technology that had not been known in this region until now. In spite of the local features, the typo‐technological traits of the artefacts suggest that at least part of them resemble in some way the Acheulean techno‐complex, but there are still many questions remaining on the age of these artefacts.  相似文献

In September 2014, the University of New England (UNE), Australia, began a three‐year programme of archaeological fieldwork and post‐excavation analyses focused on the site of Saruq al‐Hadid. In this paper, we present the initial results of our current field and laboratory research particularly related to site stratigraphy and formation processes, relative and absolute chronology, and the preliminary results of various programmes of post‐excavation analyses including archaeobotanical, zooarchaeological, ceramic and archaeometallurgical studies. These studies provide new data to build into the archaeological understanding of Saruq al‐Hadid that has, to date, focused largely on intensive excavation.  相似文献

The managers of a growing wall of money are continuously searching for investment opportunities. The financialization literature describes how this mobile capital puts pressure on commodities, debt, public services and economic activities to transform into investable, tradable, financial products. Regarding real estate, these investigations show how opaque, local, non-standardized goods, highly depending on both local legislation and developments, have been transformed into liquid, globally traded financial assets. By analysing the real estate investment strategies of Dutch institutional investors since the 1980s, this paper shows how a quantitative framework increasingly provides the basis for institutional investors’ real estate investment strategies. Direct ownership of properties has been exchanged into shares of properties, that is, fictitious capital, creating an impetus for ‘objectified numbers’ to measure the performance of these indirect investments. As knowledge about real estate has been outsourced, Dutch institutional investors now perceive real estate increasingly as ‘just another asset class’, thereby increasing leverage and volatility. This paper not only shows how finance ‘financialized’ itself by adopting a quantitative investment perspective, but it also offers an empirical account on how investment properties are transformed into financial assets that put pressure on state agencies to mobilize urban planning to deliver more of such assets.  相似文献

Acclaimed by the Parisian Surrealist circles in 1948, Malcolm de Chazal, the French-speaking Mauritian writer and painter, opted for unchartered literary territories in his subsequent works. In the 1950s, he wrote a collection of dramas that tended to decentre his writing practice towards Asian perspectives. References to Indo-Mauritian culture assuredly provided him with a major source of inspiration to deliver a culturally hybrid theatre. Yet Tibet may seem at first a rather unlikely referent in his work. One can nevertheless demonstrate by comparing the author’s numerous references to Tibet that it is not only meaningful in his entire work but also that it is a central and neglected aspect of his geo-literary agenda.  相似文献

Abstract

The aim of this article is to shed some light on issues of territorial development and of rural development and to identify what links and opposes them. Indeed, everything pushes towards joining these two dimensions, which for a long time seemed disconnected. On the one hand, the policies targeting rural areas explicitly include the territorial dimension, while the distinction between rural and urban is getting blurred. In the meantime, decentralization, subsidiarity, the regionalization of agriculture, short circuits and local foods take place in parallel with the generalization of an urban model. Finally, we find that regional sciences are paying increasing attention to rural and agricultural dimensions, while studies concerning rural questions are starting to consider territorial issues. The first section of the article provides a critical presentation and attempts to define and distinguish the notions of development, territory and the rural. The second section addresses questions of regional and territorial development by presenting the main theories and public policies and concludes with a discussion about the possibilities of reconciling the theories and the policies. The third section follows the same structure, applied to the question of rural development, from analyses to grass-roots policies.  相似文献

A range of experiments were conducted in an attempt to create tar from the bark of Betula pubescens (downy birch) using an aceramic dry distillation process. Fire structures based on small pits and small kiln-like mounds were explored with a focus on fire intensities and differing burn times under field-based conditions. Heat penetration presented itself as an all-important factor, and the depth of the construction of the structures and features was considered to directly correlate to the impact of the heat. Single variable experiments confirmed that the necessary reducing atmosphere was achievable despite friable soil, but that heat would not penetrate a 50- to 80-mm-deep layer of grass turf. The evolution of structures from pits towards a raised type resulted in kiln-like structures which proved more successful. Though the experiments did not successfully produce tar as a finished product, they did lead to a better understanding of the dry distillation process of the established technology of birch bark tar extraction in aceramic societies.  相似文献

Bells of copper and copper alloys and gold–copper alloys were deposited in events at the Cenote Sagrado at Chichén Itzá, Mexico during the site's primary occupation (ad 750–1050) and in later centuries. Housed in three museums in the United States and Mexico, bells (n = 38) were evaluated for traces of fabrication and alteration using Vis–UV–IR optical microscopy. Bulk compositions were determined through p‐ED‐XRF. Phases and compositional variation by depth were characterized through XRD and RBS. The technological styles of bell groups were ascribed to communities of metallurgical practice, from West and Central Mexico to Costa Rica and Panama.  相似文献

Xiaoshan in Zhejiang Province was an important ceramic production area in ancient China. During recent years, local archaeologists have found a number of mound tombs dating to the Zhou Dynasty and the Spring and Autumn period. Many shards of stamped stoneware and proto‐porcelain have been unearthed from these tombs. In this paper, we report how we collected ceramic shards from tombs and samples from local ancient kilns as reference materials in order to clarify their relationship. We have used the energy‐dispersive X‐ray fluorescence technique to analyse the chemical composition of the ceramic samples. The results indicate that some of the tomb artefacts may be imported from other production areas. We infer that the other tomb samples were produced at local kilns, but due to production process–related compositional differences, there are small differences in chemical composition between different categories of samples.  相似文献
